使用此代码
import sense
import json
sense.api_key = '...'
node = sense.Node.retrieve('........')
feed = node.feeds.retrieve('presence')
events = feed.events.list(limit=1)
result = json.dumps(events,indent=1)
print result
我得到像这样的JSON-Feed:
{
"links": {...},
"objects": [
{
"profile": "GenStandard",
"feedUid": ".....",
"gatewayNodeUid": ".....",
"dateServer": "2015-02-28T09:57:22.337034",
"geometry": null,
"data": {
"body": "Present",
"code": 200
},
"signal": "-62",
"dateEvent": "2015-02-28T09:57:22.000000",
"type": "presence",
"payload": "2",
"nodeUid": "....."
}
],
"totalObjects": 875,
"object": "list"
}
我如何检查'body'是否'存在'(或'代码'是'200')?我的脚本应该返回TRUE或FALSE
更新
如果我按照答案中的建议添加此代码,它可以正常工作:
d=json.loads(result)
def checkJson(jsonContents):
bodyFlag = True if "body" in jsonContents["objects"][0]["data"] and jsonContents["objects"][0]["data"]["body"] == "Present" else False
return bodyFlag
print checkJson(d)
答案 0 :(得分:5)
你也应该检查一下是否存在正文密钥。
def checkJson(jsonContents):
bodyFlag = True if "body" in jsonContents["objects"][0]["data"] and jsonContents["objects"][0]["data"]["body"] == "Present" else False
codeFlag = True if "code" in jsonContents["objects"][0]["data"] and jsonContents["objects"][0]["data"]["code"] == 200 else False
return bodyFlag or codeFlag
print checkJson(result)
答案 1 :(得分:3)
d = json.loads(results)
objs = d["objects"][0]
# see if any code is either == 200 or "body" is a key in the subdict
return any(x for x in (objs["data"]["code"] == 200,"body" in objs["data"]))
